Do Landlords Have to Pay for Mould Removal?

Is the landlord always responsible for mould removal?

In the large majority of cases, yes. Landlords are responsible for mould removal whenever the mould is linked to the condition of the building rather than to how the tenant lives. That covers leaks, penetrating damp, rising damp, failed pointing, blocked gutters, cold bridging and ventilation that was never adequate in the first place.

The key legal test is not who noticed the mould, but what caused it. If the root cause is a defect the landlord has a duty to repair, the landlord pays for both the repair and the mould removal that follows. Blaming the tenant for condensation is common, but it only holds where the property was capable of being kept dry and warm and the tenant genuinely failed to do so.

What does the law say about landlords and mould?

Several pieces of law place the responsibility for damp and mould firmly on the landlord. Together they mean a landlord cannot simply ignore mould or push the cost onto the tenant when the building is at fault.

• Landlord and Tenant Act 1985: requires landlords to keep the structure, exterior and installations such as pipes and drainage in repair.
• Homes (Fitness for Human Habitation) Act 2018: requires rented homes to be fit to live in, and serious damp and mould can make a home unfit.
• Awaab’s Law: requires social landlords to investigate and fix damp and mould hazards within strict, legally set timescales, with the framework expected to extend across the sector.
• Renters’ Rights Act: strengthens tenant protections and applies the same fitness and hazard duties more widely, making it harder for landlords to delay action.

How do you tell if mould is the landlord’s fault or the tenant’s?

You tell them apart by tracing the source of the moisture, because the cause decides who pays. Condensation mould and building-defect mould can look identical on the wall, so the pattern and the source matter more than the appearance.

Signs that point to a building defect the landlord must fix:

• Damp patches or tide marks low on walls, suggesting rising damp.
• Staining spreading in from an outside wall or around a window, suggesting penetrating damp.
• Mould appearing after a roof, gutter or plumbing problem.
• Cold, damp corners and ceilings caused by missing insulation or cold bridging.
• No extractor fan or trickle vents in a kitchen or bathroom.

To check quickly for yourself before calling anyone:

1. Note where the mould sits: high corners often mean condensation, low tide marks often mean rising damp.
2. Check whether it is worse near a specific pipe, window or external wall.
3. Look for recent leaks, overflowing gutters or damaged render outside.
4. Confirm whether kitchens and bathrooms actually have working ventilation.
5. Photograph everything and record dates, as this evidence supports any later claim.

What can a tenant do if the landlord refuses to pay?

If a landlord refuses to pay for mould removal, the tenant should report the problem in writing and keep a dated record of every message. A written report starts the clock on the landlord’s legal duty to act and creates the evidence trail that matters later.

If nothing happens, tenants can contact the local council’s environmental health team, who can inspect under the Housing Health and Safety Rating System and issue improvement notices. An impartial mould remediation and diagnostic report is often the decisive piece of evidence, because it identifies the cause rather than leaving it to argument. Once the cause is documented, disputes about who pays tend to resolve quickly.

When should I call in a specialist?

Call in a specialist as soon as the cause of the mould is unclear or disputed, because that is exactly where a proper survey settles the question. Damp & Mould Solutions UK diagnoses the cause of damp and mould rather than selling remedial work, so the finding is led by evidence, not by what someone wants to sell.

A survey begins with full moisture mapping across the whole affected area, so the true extent is measured rather than guessed. Thermal imaging and non-destructive, non-invasive leak detection using acoustic and tracer methods are used to trace a source before anything is opened up, which avoids needless damage. Every survey ends with a root-cause diagnosis before any remedial work is agreed.

We confirm the price on a written quote once we understand the problem. Our Damp, Mould and Water Damage Assessment (what many people call a damp survey) includes full moisture mapping, root-cause diagnosis and a written, insurance-ready report with a photographic evidence appendix, clear findings and prioritised recommendations. If a leak needs tracing to its exact source, we quote for leak detection separately. To get an initial view, call 020 3051 8478 or send photos via WhatsApp, and a surveyor can tell you what is likely going on before anything is booked.

If you've got damp, mould, or a leak, you already know it needs sorting.

The longer it sits, the worse it gets. Get in touch and we will agree a date with you. If it is urgent, say so when you call.
